COVER FOR BLANK BOOKS.

Specification of Letters Patent.

Patented July 28, 1914;.

Application filed January 29, 1913. Serial No. 745,000.

To all whom it may concern:

Be it known that I, JOHN W. GEARHART, a citizen of the United States,residing at Fresno, in the county of Fresno and State of California,have invented new and useful Improvements in Covers for Blank Books, ofwhich the following is a specification.

This invention relates to covers for blank books, and it has for itsobject to produce a simple and improved cover adapted to receive afiller, such as a stenographers note book to afford protection for suchfiller.

A further object of the invention is to produce an improved constructionof the cover whereby the leaves of the filler will lie flat tofacilitate writing, irrespective of the grade or quality of paper thatmay be used.

A further object of the invention is to produce a book cover comprisinga filler clamp in connection with two hingedly supported side membersand simple and improved means whereby one side member of the cover islocked in fixed relation to the filler clamp, while the other sidemember of the cover is free to move.

A further object of the invention is to simplify and improve theconstruction of the side members of the cover, said side memberscomprising metallic frames which are integral with the sleeves of thehinges, thereby reducingthe number of parts required in the constructionof the device, and avoiding the use of rivets and other fastening andconnecting members whereby rough and uneven surfaces would be produced,and whereby the cost of manufacture and assemblage of parts would beincreased.

lVith these and other ends in view which will readily appear as thenature of the invention is better understood, the same consists in theimproved construction and novel arrangement and combination of partswhich will be hereinafter fully described and par ticularly pointed outin the claims.

In the accompanying drawings has been illustrated a simple and preferredform of the invention, it being, however, understood that no limitationis necessarily made to the precise structural details therein exhibited,but that changes, alterations and modifications within the scope of theclaims may be resorted to when desired.

In the drawings,--Figure 1 is a perspective view, showing a portion of acover constructed in accm'dam'e with the invention in a simple andpreferred form thereof, one side member of the cover being raised. Fig.2 is a transverse sectional view taken substantially on the line 2-2 inl ig. 1. Fig. 3 is a horizontal sectional view taken substantially onthe line 3-3 in Fi 1. Fig. l; is a perspective detail view of one of thelocking dogs. Fig. 5 is a transverse sectional view similar to Fig. 2,but illustrating a modified form of the invention. Fig. 6 is a sectionalview similar to Fig. 3, illustrative of the modified form. Fig. 7 is aperspective view of one of the locking dogs of the modified form of thedevice. Fig. 8 is a perspective detail view of the metallic frame of oneof the side members of the cover. llig. S) is a longitudinal sectionalview of said frame together with its filler. Fig. 10 is a transversesectional view taken on the line 10-10 in Fig. 9.

Corresponding parts in the several figures are denoted by likecharacters of reference.

The improved cover comprises side members 15 in the cmistructitm ofwhich there is included rectangular metallic frames 16 having arms 1.7which are terminally bent or coiled to form sleeves 18 which are soarranged that when the cover members are assembled, the sleevesassociatlal with the two cover members will lie in alternate order andserve for the reception of a pintle 19 about the axis of which the cover.i'nembers may turn.

The tiller clamp as herein shown consists of a yoke 30 having limbs orside members J11. pivotally engaging the ends of the pintle, said clampbein positioned between the cover members. lhe filler clamp includesarms which are terminally bent to form books .23 adapted to engagenotches 24 in the side edges of the filler A, which latter consists of astack of leaves which are suitably assembled in any cimvenicnt andsuitable manner. It is desired to be understood that the c mstruction ofthe tiller clamp as regards the manner of connecting the fillertherewith may be varied indefinitely, the form shown being merely forthepurpose of iluustration ()ne of the sleeves '18 of each cover member isprovided with a notch or recess 25 producing a cam-shaped edge 26 thatextends outwardly from the arm 17 by the bending or coiling of which thesleeve 18 is formed. Pivoted on the yoke 20 of the filler clamp areoppositely disposed dogs 27 each provided with a terminal hook 28 havinga beveled engaging edge 29, and each provided also with an arm 30extending into the notch or recess 25 of one of the sleeves 18 so as tolie in the path of the cam edge 26, The hook or detent of each dog 27 isadapted to engage one of the arms 17 extending from each cover member.Suitably arranged pins or steps 31 are associated with the filler clampfor the purpose of limiting the movement of the dogs 27. When both covermembers are closed down upon the filler,the arms 30 of the two dogs willbe free to play in the recesses 25. When the book is laid down flat on adesk or table in position for use, and the uppermost side member of thecover is raised, the cam edge 26 associated with such cover member willbear against the arm 30 of the dog associated therewith, and theterminal hook 28 of such dog will be positively moved into lockingengagement with an arm 17 associated with the lowermost cover member,thus locking the filler clamp in fixed relation to such lowermost covermember and compelling the filler A to lie flat thereon. This operationwill obviously take place which ever of the two cover members happens tobe uppermost, and it follows that when the end of the book is reachedand the book is closed and reversed so as to place the cover memberwhich was previously at the bottom, on top, the raising of such covermember will cause the filler clamp to be: placed in locked relation tothe cover mem The bevel; 29 of the engaging edge of the hook 528 will}ber which is now at the bottom.

permit the topmost cover member to be raised without being obstructed bysuch hook.

Under the modified construction of the device illustrated in Figs. 5, 6and 7, the recesses 25 are omitted, and the dogs which are heredesignated by 27 are in the form of bell cranks having arms 30 whichserve by gravity to hold the terminal hook 28' of one of the dogs inlocking engagement with an arm 17 of the lowermost cover member and innon-engaging relation to an arm 17 of the topmost cover member which maythus be freely raised. Pins 31 extending from. the yoke of the fillerclamp within the angles of the bell cranks serve to limit the movementof said bell cranks in any direction. Except that these dogs areoperated by gravity instead of being positively actuated by the camedges 26, the operation is precisely as previously described.

It will appear from the foregoing that the two cover members of thedevicewill be of precisely similar construction, enabling them to beconveniently connected and assembled by the pintle l9. Said cover 'menrbers have been shown as consisting of rectangular frames 16, struck upor stamped from sheet metal, such as well tempered steel of suitablegage, thus enabling the arms 17 having the terminal sleeves or coils 18to be formed integral therewith. Each of said frames is provided withstruck up inclined or beveled flanges at the free edges thereof for thereception of a coverboard B which may be durably but inexpensivelyconstructed of pasteboard, indurated fiber or any other suitablematerial, thus presenting a cover member possessing exceptionallydesirable qualities in the way of strength, durability, rigidity, andthe like.

The filler A to be used in connection with. this improved cover devicemay be constructed in any desired manner, and the leaves may be weakenedin the manner shown in Patent No. 987,619, previously granted to me, forthe purpose of causing said leaves to lie fiat when turned, or any otherspecial construction may be resorted to. No limitation is made asregards the manner of connecting the filler with the clamp for thepurpose of retaining it in position between the side members of thecover.

Having thus described the invention, what is claimed as new, is

1. A blank book cover comprising side members, a pintle with which saidside members are hingedly connected, a filler clamp supportedpivotally-on the pintle between the side members, and movable devicesfor locking oneside member in fixed relation to the filler clamp whilethe other side member is free toinove.
